As disagreements over funding for President Donald Trump's long-promised border wall brought the government to the brink of a shutdown Friday, Trump tweeted a rendering he described not as a wall but rather a "Steel Slat Barrier."

The rendering highlights spikes on top of the proposed barrier, which Trump described as "beautiful" and "totally effective."

The rendering and Trump's omission of the word "wall" comes as Democrats have signaled more likely cooperation in approving money for "fencing" rather than a "wall."

It's something Trump has addressed on Twitter before: "The Democrats, are saying loud and clear that they do not want to build a Concrete Wall - but we are not building a Concrete Wall, we are building artistically designed steel slats, so that you can easily see through it," he tweeted Tuesday.

On Thursday, Trump used "wall" and "steel slats" interchangeably in a Tweet: "The Democrats, who know Steel Slats (Wall) are necessary for Border Security, are putting politics over Country."

And during a bill signing Friday, Trump went as far as saying he didn't care what people called the project: "One way or the other we're going to get a wall, we're going to get a barrier, we're going to get anything you want to name it. You can name it anything you want."

As border wall funding took center stage this week, others took their suspicion of the project to another level: Several campaigns have been started to raise money for ladders and escalators to supposedly circumvent the proposed wall.
